I can only snap my fingers if I reinforce my middle finger by wrapping my index finger around it. My partner of 16 years just found this out about me while our daughters (4 & 7) were attempting to snap. And he said (playfully) that I was weird.
I don't know anyone else that does this, but it's definitely something that is very noticeable.
There are other "weird" things about me that are maybe better classified as non-mainstream, but IDK that it means they are weird. Particularly with child rearing. I nursed both of my kids until their 3rd birthday. Since they are 2 years apart, this means I also tandem nursed for a while. I also practiced an alternative to diapers that involved holding my newborns over tiny potties and making cue noises so they'd basically pee and poo on command. But really, a lot of people do these things. Just not most of them.
I don't drink or eat meat but I love brewpups and steakhouses.
And I'm kind of unusually small. I mean, there are plenty of adults out there that are under 5 feet and 100 pounds (I'm 4'10.5" and hover in the high 90s.) Just thinking of it because I was at the Y with my kids swimming in their "kid" pool, in which the deep end is 5 feet. My almost independent swimmer 4 year old, but not quite, was worrying me by wanting to swim in the middle of the deep end. "You have to stay near a wall! Mommy can't stand here to help you if you need someone to grab! Stay near the wall, please!" I'm like, treading water and out of breath and there's another mom right next to me, standing up with the water comfortably at her collarbone playing with her kid.
